How many people are affected/at risk by McCune-Albright syndrome (MAS)?

Number of People Affected

MAS is rare, affecting between 1 in every 100,000 to 1 million live births worldwide.1

Who is at risk?

Because the genetic change or mutation that causes MAS occurs at random very early in fetal development, MAS is not an inherited disease, meaning parents do not pass it on to their children.1

MAS likely occurs equally in males and females.
